Method for sending RLC PDU and allocating radio resource in mobile communications
system and RLC entity of mobile communications |
(57) Disclosed is a transmission of a RLC STATUS PDU using a limited radio resource by
MAC and RLC layers in a long term evolution (LTE) system. In case where the MAC entity
prioritizes logical channels for allocating the radio resource to each logical channel,
the MAC entity is allowed to allocate radio resources based upon the size of a RLC
STATUS PDU to be sent from the RLC layer and also the RLC layer is allowed to use
the STATUS PDU prior to RLC data PDUs upon using the allocated radio resource, such
that RLC protocols can be avoided from coming in a deadlock situation due to a non-transmission
of the STATUS PDU.
